い。Conventionally, there are various methods for producing a clad metal sheet by hot rolling, but all of them are produced by hot rolling from a slab by an assembling method, a casting rolling method, an explosive deposition method or the like. FIG. 13 shows a slab prepared by the assembling method, in which the joining material 4 and the base material 6 are arranged on both sides of the peeling material 2 as the center, and the peripheral portion 8 is welded. Further, the casting rolling method is disclosed in
As disclosed in 58-23534, the composite material 4 is suspended in the mold, the molten metal of the component of the base material 6 is cast, and the slab is rolled to form a
It is a slab as shown in the figure. In each of the slabs, the laminated material 4 and the base material 6 are pressure-bonded during hot rolling. However, since the base material 6 and the laminated material 4 have uniform plate thickness, the clad ratio of the clad steel plate after the hot rolling is constant. Therefore, steel sheets having different cladding ratios in the same steel sheet cannot be obtained.

However, the cost will be enormous if the whole is manufactured by using the cladding steel plate with the required thickness of the immersion part. Alternatively, there are methods such as welding cladding steel plates with different cladding ratios, or assembling the entire tank with cladding steel plates with the same cladding ratio, and then overlaying the necessary parts, but in both cases welding work is difficult and defects occur. There is a problem of.
